Raw fMRI data for “Brief Exposure to Obesogenic Diet Disrupts Brain Dopamine Networks”

[a] LEGEND

LF = rats fed low-fat diet
HF = rats fed high-fat diet
saline = rats injected with saline
AMPH = rats injected with amphetamine

[b] GROUP ASSIGNMENT

LF_AMPH   = {'R06' 'R10' 'R11' 'R17' 'R19'}
LF_saline = {'R13' 'R18' 'R20'}
HF_AMPH   = {'R29' 'R31' 'R39' 'R53' 'R55'}
HF_saline = {'R30' 'R37' 'R52' 'R54' 'R56'}

[c] DETAILS

For all rats EXCEPT for R52 to R56:

- each fMRI data set contains 60 images (acquisition time = 1 min per image)
- first 10 images (#1-10) represent pre-injection baseline
- injection of AMPH or saline took place after 10th image
- images #11 to #40 represent 30-min post-injection response curve
- last 20 images not used in the analysis

For rats R52, R53, R54, R55, and R56:

- each fMRI data set contains 50 images (acquisition time = 1 min per image)
- first 10 images not used in the analysis
- next 10 images (#11-20) represent pre-injection baseline
- injection of AMPH or saline took place after 20th image
- images #21 to #50 represent 30-min post-injection response curve
